How did the White Sox do in 2006? Maybe we should make statements based on that? The Giants and Angels (even with their singular down season) have been perennial playoff machines. That's what drives their attendance.

You're right that the Padres draw, but San Diego is a weird city in that it's got a large military population that really helps with attendance, and they host several military themed games and programs because of it.

A more apt comparison for the Dodgers would be the Yankees. And even that's not as good because the Dodgers don't share L.A.
My point is there's a million things to do in California compared to cities like Atlanta or any of the smaller cities in the midwest. Add in way worse traffic, and regular trips to the ballpark are not really worth it unless the teams are playing well.

And all the teams, besides Oakland, draw well regardless of that. Everything above that is you trying to excuse facts away to fit your nonsensical argument.
